The main purpose of the authority file of published patent documents is to allow all interested parties to assess the completeness of the available patent documentation from the intellectual property office (IPO) that generated the authority file.
On this page, you can find the most recent authority files compliant with WIPO Standard ST.37 which have been provided by the IPOs to the International Bureau of WIPO or links to the webpages where such authority files are hosted. The recommendations on data elements, structure and format of authority files are provided in WIPO ST.37.
The icons included within the table indicate the file type of the authority file and will initiate a download. The exception is 'HTML' which indicates that the Office is hosting the file locally and you will leave the WIPO website to go to the linked HTML page.
